掃描文件夾時出現各種錯誤

請不要將其標記爲重複，因爲我查看了此錯誤的其他問題，但我仍然無法弄清楚。掃描文件夾時出現各種錯誤

我正在製作一個基本掃描程序，用於掃描指定給它的目錄，並刪除所有超過90天的子目錄。下面是代碼：

import os, sys 
import time 
import shutil 
from Tkinter import * 
import Tkinter, Tkconstants, tkFileDialog 



now = time.time() 
home1 = os.path.join(os.environ["HOMEPATH"], "Desktop") 
desktop = os.path.join(os.path.join(os.environ['USERPROFILE']), 'Desktop') 

root = Tk() 
root.withdraw() 
path = tkFileDialog.askdirectory(initialdir=desktop, title="Select folder to scan from: ") 
path = path.encode('utf-8') 

for x in os.walk(path): 
    for folders in x: 
     while os.stat(folders).st_mtime < now - 90 * 86400: 
      q = raw_input('Folder(s) found. NOTE: This will delete all directories or subdirectories in the folder. Do you want to remove?(y/n) ') 
      if str(q) == "y" or str(q) == "Y": 
       shutil.rmtree(path, ignore_errors=True) 
       print 'Successfully deleted folder(s)' 
      elif str(q) == "n" or str(q) == "N": 
       print 'Folders not deleted.' 
       sys.exit() 
     else: 
      print 'No folder(s) over 90 days'

以下是完整的回溯：

Traceback (most recent call last): 
File "C:/Users/Bill/Desktop/limitScanner/scanner.py", line 20, in <module> 
while os.stat(folders).st_mtime < now - 90 * 86400: 
TypeError: coercing to Unicode: need string or buffer, list found

編輯：當我使用我的程序與多個子文件夾，如桌面文件夾中的文件夾，它給了我下面的錯誤：WindowsError: [Error 2] The system cannot find the file specified和第一個文件夾的名稱。我正在使用python 2.7.13。任何人都可以幫忙嗎？任何幫助廣泛讚賞。

os.walk返回3元組(dirpath, dirnames, filenames)。你目前的方法迭代3元組，在第二次迭代中給出目錄名稱列表dirnames。

但是，你只能在dirnames感興趣：

for _, dirs, _ in os.walk(path): 
    for folder in dirs: 
     ...

我的程序似乎凍結時這樣做 – Bill

@Bill它被卡在while循環中。您應該使用* if *塊來代替。 –

工作對我來說：

import os, sys 
import time 
import shutil 
from Tkinter import * 
import Tkinter, Tkconstants, tkFileDialog 

now = time.time() 
home1 = os.path.join(os.environ["HOMEPATH"], "Desktop") 
desktop = os.path.join(os.path.join(os.environ['USERPROFILE']), 'Desktop') 

root = Tk() 
root.withdraw() 
path = tkFileDialog.askdirectory(initialdir=desktop, title="Select folder to scan from: ") 
path = path.encode('utf-8') 

for _, x ,_ in os.walk(path): 
    for folders in x: 
     if os.stat(os.path.join(path,folders)).st_mtime < now - 90 * 86400: 
      q = raw_input('Folder(s) found. NOTE: This will delete all directories or subdirectories in the folder. Do you want to remove?(y/n) ') 
      if str(q) == "y" or str(q) == "Y": 
       shutil.rmtree(path, ignore_errors=True) 
       print 'Successfully deleted folder(s)' 
      elif str(q) == "n" or str(q) == "N": 
       print 'Folders not deleted.' 
       sys.exit() 
     else: 
      print 'No folder(s) over 90 days'

我適應了os.walk(path)輸出摩西說，改變了while到if並添加(os.path.join(path,folders)，所以os.stat(...)可以找到有問題的文件夾。

for _, x ,_ in os.walk(path): 
    for folders in x: 
     if os.stat(os.path.join(path,folders)).st_mtime < now - 90 * 86400:
